I personally wouldn't, the two harnesses may have a tendency to squeeze together around the neck on impact.
surely not because of the holes in the seat wouldn't allow it.... ?

and surely this would be a problem with 3 point harnesses too then
which, as far as i am aware, are as safe as 4 point ones when used with proper buckets with harness slots

Why not get your mum to wrap gaffer tape around your body and the seat? That'd be safe as houses - but you don't see THAT in WRC/F1 cars.

i had a crash with normal belts , i slipped out of them , they were tight and tensioners went off, but my car spun 180 degrees.
personally i think harnesses are very uncomphy and a pain in the arse

when i was at school we had the police come round telling us about road and car safety
he told us that over about 40 to 50 wearing a seat belt can be worse than not because as the tensioner goes the shoulder strap can break ur collar and ribs. and because of how the belt is it pushes the bones into your lung and can puncher them
sum smart arse asked about raceing harnesses and he said that they are loads better than standard belts because as you crash they still can break your collar but your ribs and lungs are alot safer

Harnesses (if fitted correctly) are miles safer than standard seatbelts - anyone saying otherwise is talking out their arse.
Harness shoulder straps must be mounted a maximum of 45 degrees from exit of the holes on your bucket seat, so using the existing seatbelt mounts will be fine. I wouldnt recommend using one eyebolt for both harnesses though as like Ian said, its putting a lot of strain on one area of the shell. 3pt harnesses are mounted in the one area and are safe enough, but you wouldnt catch me using them - minimum Id consider sitting in is 4pt. It really depends on how much you value your life.
If you roll the car with your harnesses mounted to the C pillar, they can become loose as the C pillar is very prone to collapsing.
As for the bottom two mounts, make sure these are mounted just behind where your arse is. Too far forward (forward of your arse) and they are not so effective and too far back means you can slide down through the harnesses in a front impact.
Once you've got all that sorted, you still need to make sure the harnesses are tight enough to really hold you in the seats, but just loose enough not to cut off circulation. Any looser and they'll just snap your collar bone in an impact.

No one was saying that harnesses weren't safe - just where they're mounted (as you've said) is the MOST important thing....

No - the holes in the seat would just collapse, there's no lateral strength at all.

Scrutineers will pass this as its deemed "safe enough" but again, it depends on how much you value your life. For the sake of mounting an eyebolt, its a lot stronger and safer.
